Let A be a regular ring (for example, the polynominal ring in a finite number of indeterminates over a field). Let P be a prime ideal in A. In [1] Hochster raises the question whether it is possible to give conditions on A/P (for example, A/P Gorenstein) which imply that the powers of P are P-primary, (i.e. Pn = P(n) for all n).- Graded Gorenstein Rings

Hochster-Ratliff ([1] Proposition 4.10) have proved the same theorem without the projectivity condition. Here we prove that if A is Gorenstein at all maximal ideals containing M then A is Gorenstein.- On the Fibres of Blowing Up
